guide strips 4 at each of its opposite sides defining grooves or channels within which the upper sash 2 and lower sash 3 are slidable between open and closed posi-, tions. At its bottom the window is provided with a sill 5 inclined downwardly and outwardly, and at its inner` surface the window has trim members 6 including a horizontal stool member 7, preferably positionedrat a level above the upper surface of the uppermost end of the sill 5, as illustrated in Fig. 2. The window is adapted to receive a frame 8 outwardly of the outer vertical ribs4 thereof, which frame may either carry glass panes and constitute a storm sash or may carry window screening, as Well understood in the art. p

My new device comprises a pair of similar ventilator frame members adapted to seat against opposite vertical sides of the window frame, as illustrated in Fig. 3. Each of these frame members preferably constitutes a vertically elongated metal member of substantially uniform cross-section and of substantially channel shape. Thus each member has a base 12 which is substantially dat and whose width will preferably be substantially equal to the spacing between the outermost edges of the guide strips 4 which guide the lower sash 3. From its opposite margins extend substantially parallel portions 13 and -14 which are slightly different in width, the member 13 as here shown being slightly wider than the member 14.v Substantially parallel but slightly offset inwardly projects` ing parts 15 and 16, which are parallel to the base 12, project from the outer ends of the parts i3 and 14, vrfcspectively. Substantially parallel ilanges i7 project from the inner ends of the members 1S and i6, the same extending substantially perpendicular to the base plate V12 and having their outermost surfaces spaced apart a dis-v tance substantially equal to the spacing between the members 4 which guide the lower sash 3. This metal channel member will preferably be of a length slightly less than the height of the lower sash 3, although it may' be of any length found suitable and may be substantially shorter than the sash 3. The upper and lower edges of the channel member will preferably be inclined to fit snugly relative to the inclined sill 5 and the inclined bottom surface of the window sash 3.

Each of the channel base members 12 mounts a plurality of brackets or carriers. Thus each of these carriers preferably has a base 21 pivoted intermediate its ends to the channel by means of a rivet or like pivot member 22 extending therethrough and preferably through parts 12 and i5 of the channel as illustrated in Fig. 3. 'The pivot 122 ywill preferably be located substantially cena trally of the length of the member 2i. project lengthwise of the plate 21 in parallel relation and are interconnected at one end by an end plate 24. Thus each of the members .Zi-24 constitutes a socket adapted to receive one end marginal portion of an elongated glass panel or louver 25. It will be understood that cushioning material, such as sheet rubber, felt or the likegmay be carried by the channel-forming members 23, 24 to cushion the ends of the glass panels carried thereby, and it will also be understood that'r flanges or retainersZ may be provided at the upper ends of each of the sockets to retain the glass panels against release, as illustrated in' Fig. 9. A sutlicient number of sockets and panels will be provided so that the space between the'lower sashV 3 in its elevated position, as illustrated in Fig. 2, andthe sill, which is determined by the length of the channel 1 2, will be completely spanned by the aggregate of the win-vy ldow panel members 25 when the latter are in the [full line closed position illustrated in Fig. 2. At the same time, the glass panels are of such width that they mayA be swung to substantially horizontal position, asjillus-` trated in dottedlines in Fig; 2, to provide mai'timum ventilation or air movement through the space btwcex'i Side anges 2.3` I

against the inner surface of the lower portion of the frame of the sash 3. Aplateportion 47 projects forwardly and slightly downwardly from the junction of the parts 45 and 46 and is adapted toV bear against the inclined bottom face of the lower member of'the lower sash 3.` An upwardly projecting tongue or lip 48 is stood that the channel members and the sockets pivoted' 'y thereto constitute preformed units which are handled separately and must be formed in right and left constructions so as to be inserted in place at opposite sidesV vof the window. After insertion of the channels inpla,

the glasspanels 25 of'proper length to span the window opening are inserted in the socket members 23, 24 so that the glass panels 'constitute means for holding Y the `frame parts in proper spaced relation.

Means are provided for simultaneously and equally formed at the free end of the part 47 and is adapted to bear against the outer face of the lower member of the" lower sash 3. Thus the member :4I-4S cooperates with the window frame, the lower window sash, and the frame members of my device to hold the latter in proper posi- Vtion when the vlower member of the sash 3 bears thereagainst and when the shoulder 43 bears against the part 7 of the window frame. In thisconnection it will be vobserved that the plate 42-` projects inwardly beyond frame partis 12, 14 and terminates in the paths of pivotal movement of the inner ends of the glass panels 25, as

pivoting the glass panels or louvers. Such means ,may4 Y be located at one only of the channels and is preferably` constructed substantially as illustrated in Figs.3 and 4'. An elongated rod'or4 bar 31 of a length less than the ovrallrlength of the. member 12 is slidably received within the `channel chamberfdened by the parts 12,714, 16, and preferablyis located in substantially face engagement with the part 16 with its innermost edge adjacenttol or bearingjagainst Vthe member'14. Two vor moreV seen in Fig. 3, so as to form a barrier preventing sliding Aremoval of those panels from the receiving sockets 23 and 24 in a selected range of the open positions of said sockets and louvers. Positive means to prevent disassembly of these parts can be provided very simply in the nature of a stick or bar 49 bearing against the top member of the lower sash 3 and against the bottom of the .top member of the window frame, so as to prevent raising of the `lower sash from the position illustrated in Fig. 2." i

pins 32, anchored Vat their opposite ends at partsk12 and Y 16, 'are located adjacent the outer edge of the member f 31 for engagement with said edge to guide the same and,

in cooperation with the part 14, hold the same in substantially vertical position, but in a position capableof free sliding motion. A plurality of links 33, equal to the number ofsocket members k23, 24, are pivoted at 34 at one "end to the bar 31 in substantially equally spaced relation juxtaposed to the respective socket members 23, 24. At its opposite end,.eachof the links 33 Any suitable means may be provided for adjusting the position of the pane-carrying sockets 23, :24. One such means is `illustrated in Figs. 2 and 6. In this construction an elongated slot extends vertically Ain the member 12 at 51 in register with the vertical bar 31'.` Along the opis connected by a pivot pin 34 withV a lever 35 which is lixedly mounted upon the pivot pin-22, as by means of a cross-pin 36V extending'through an aperture therein and inpin 22. It will be understoodthat the pin 22 is tixedlylelated to the plate 2i of the glass-receiving socket as .by means of splines 37 or lock members, so

that movement or swinging of one of the parts 21 or 35 will result in `similar and equal rotative movement or swinging of the other of said members 35 and 21. The levers 35 and linkst33 may be arranged in any manner found suitable and the relation ,ofV the partswill be such that longitudinal movement of the barV 31 will produce similarand equal rocking or swinging movement of each of the pane carriers "23, 24, Thus the members may be arranged substantially as illustrated in Fig. 4, from which it will be seen that any movement of the member 31 will equally swing the .respective panestZS between fully open and fully closed positions. v Y

Any suitable means rn y be provided for Yeffectively lockingvtheframe membersin the window frame so the same cannot be disassembled or dismantled orremoved from the lwindow trame. Each of the `frames is Vthus associated with a container member Vof the construction best illustrated Yin Fig. 5,. and preferably including a f ange141 bent substantially perpendicular from a plate y42 land cooperating therewith "to define a member of substantially angleiron shape in cross-section. The memb'er 41 Vis narrow and is adapted 'to be interposed be tween the channel part 16 and the frame part 4.A The member 42 is adapted to bear against :the inner surface ofthe channel part 14. The member 42 is located above the stool 7 and is preferably offset at 43 adjacent its lower end to deiine aY step and terminates in a tongue or lip `portion T44 which` is vadapted to bear againstthe outer edge o'f the member 7 ofT the window frame. The Amember 41 preferably terminates adjacent butV above thestep 43. The Vmember 42` is bent at its opposite V end at and Vterminatesiyin a lip 46 which is adapted. fro-bear posite sides of the slot the member 12 is provided with a series of spaced apertures 52. A bracket 53 iscarried by thesmember 31 and extends through the slot 51. In the preferred form the bracket has an upwardly project- Ving portion 54 and a substantially horizontal terminal portion 55 projecting'` inwardly fromthe member 12 and. preferably so' oriented as tobe clear of the members 23, 1

24. and the glass panels carried thereby in all operative positions thereof.` Ears 56 form a part of the bracket 53 and have pivotedthereto at 57 a latch 58 whose shape may be substantiallyrof the character illustrated in Fig. 6 and which terminates in a locking pin 59 adapted to seat in one of 'the apertures 52. If desired, the member 58 may have Vtwo pins-59 spaced apart laterally. The

opposite end portion 60 of themember 58 has pivotally connected thereto at 61 a latching lever 62 which preferably is spacedbelow the member 55 and `provided with an upwardly projecting elongated pin 6?:` around whichV A ts the lower end portion of a coil spring 64 adapted to urge `thernember 62 away fromthe member 55. The upper Vend of thev spring 64 will preferablyl be anchored suitably to the member 55. YThe arrangement of the parts is such `that the spring 64 normally .urges the pin 59 into locking position in a socket 52 when registering therewith. However, when the members 62 and 55 are grasped to rswing them toward each other against the Y action of the springthe locking pins are swung out of the sockets 52, thereby accommodating bodily `movement of the bar 31 relative to the frame 12. i i

In the eventV it is desired to disenga'ge thelatch pins 59, anVV arrangement as illustrated in Fig. 6 may be ern-4 ployed, which arrangement includes the provision of a hook member 65 which is swiveled at itsppper end to the member 55 as at a fixture 66. The lower/'end portion of the hook 65 is adapted to seatin an aperture 671in the member 62 when theparts Yare in the dotted line' position shown in Fig. 6, thereby holding theimemberl S9 retracted from the sockets V,52 in the members 12. It will be evident, therefore, that the device illustrated in Fig. 6, if associated with a number ofspaced socketsV 52, may provide for a number of fixed adjusted positionsv of the z glass panels of which onejis shown in full lines in Fig. `6.

Alternatively, the member may be unlatched completely,

as shown in dotted lines in Fig. 6, so that the panels are free to swing at all times.

One of the glass panel sockets is preferably provided with a vane 70, as illustrated in Fig. 8, extending lengthwise of the glass panel 25 carried thereby along the lower end thereof and upwardly diverging therefrom at an angle of approximately thirty degrees as illustrated. Of course, if desired, more than one of the vanes 70 may be provided. This vane serves as a means to pocket wind gusts acting against the pivoted louvres during such times as the parts are held in released position by the hook 65. lt will be understood, of course, that in this connection, the panes 25 and their sockets 23, 24 will preferably be substantially balanced about their pivot axes 22. When this occurs, wind gusts which act upon the panel 25 and the vane 70, as upon the approach of a storm, act to swing the free lower end of the associated vane inwardly, and this movement is translated through the bar 31 and associated links and levers t0 each of the other vanes 25 so as to automatically close the window upon the approach of storm conditions. Thus with this device a householder need not be concerned about leaving his home with windows open during threatening weather since the device can be adjusted as described above in unlocked position and partially open, thus allowing for ventilation. Such Ventilation can continue until such time as an increase in wind velocity or pressure automatically closes the device under storm conditions.

If desired, the device may be provided with a sealing strip upon the inner upper margin of each of the glass panels 25 thereof, as illustrated in Fig. 7. The sealing strip is preferably of channel shape, having web 75 and a pair of flanges or legs 76 and is preferably constructed of rubber or other resilient material adapted to iit the margin of the panel 25. The web 75 is preferably projected at 77 to a slight extent, and this projecting portion will preferably have an inverted groove 78 defined thereby. The strip 75 will preferably extend full length of each glass panel between the sockets which mount it, and will be of such dimensions that the projections 77 bear against the inner face of the next uppermost giass panel 25 when the device is in closed position. The device also functions when the panels are in open position. In this instance the rib defined by the undercut 78 serves as a stop to the flow of liquid which may be blown along the surface of the panel and which normally tends to enter between adjacent panels when the device is either open or closed.

It will be apparent from the foregoing construction that the device is simple in construction and can easily be mounted and dismounted. When dismounted, each of the constituent parts are generally of elongated narrow and substantially fiat character so that storage thereof can be effected within a small space. The various operative parts, of course, consist of the two channels 12 and their associated glass sockets and adjusting mechanism, two retainer members 42 and the glass panels 25. Observe that it is not necessary to employ screws, bolts or any other securing means in order to assemble the device, and, further, that it can be locked effectively by the simple expedient of employing a stick or a strut 49 to prevent raising 'of the lower sash 3 out of engagement with the retainer members 47, 45.v Because of the nature of the construction it is apparent that the members 12 and 42 can be made in standard sizes, and as such will tit windows of many different sizes, it being necessary only, to accommodate windows of different sizes, that the glass panels 25 be Vof a length to span the Window. This reduces the number of parts which a dealer must stock and adapts the devieefor mass production and distribu-l tion, thereby holding costs to the ultimate consumer at the lowest possible level.

It will be observed that the flanges 42 of the retainer members project into the path of pivotal movement of the louvers 25 when the latter are tilted toward horizontal or open position. This relation is best seen in Fig. 3. This serves as a means to retain the louvers within their receiving sockets when the louvers are positioned within a selected range of open position. Furthermore, it will be apparent that the upper part 47 of each retainer in conjunction with the anges 42 and louvers 25 overlies the ends of and thus serves positively to retain the uppermost louver, in all adjustments thereof. Since the louvers span the ventilator frame between channels 12 at opposite sides of the window frame, the ventilator frame cannot be removed from the window frame until all of the louvers have been removed. Also since the louvers so lock the ventilator frames in the window frame, and since `the upper louver cannot be removed until the retainer members 41-48 are removed, it is :apparent that the retainer members serve as means to prevent the removal of both the ventilator frame members and the panel members or louvers.

The device has a wide range of adjustment between fully open and fully closed positions and may be locked in any adjustment selected. Alternatively, by maintaining the device in unlocked position, it can be'made responsive to wind conditions, so that it will closeV automatically when storm conditions arise. Still another advantage of the device is its effective sealed condition when closed. Again, as will be apparent fromFig. 2, the device can be installed without interference with the conventional window screens mounted in the frames S. Retainer part 42 serves to guide window shades and Venetian blinds to prevent interference of the device therewith.

While the preferred embodiment of the invention has been illustrated and described herein, it will be understood that changes in the construction may be made within the scope of the appended claim without departing from the spirit of the invention.

I claim:

A ventilator adapted to be mounted in the frame of a double hung window having a lower sash slidable in vertical guideways, comprising a pair of uprightxindependent frame members each mounted in and projecting from a guideway, a plurality of spaced louver sockets pivoted to each frame member and interconnected for coordinated pivotal movement, a plurality of rigid louvers seating in said sockets at their opposite ends and maintaining said frame members seated in said grooves, each frame member having a longitudinal shoulder, and a retainer member having hooked engagementwith said longitudinal shoulder, said retainer interlitting with said sash Y at one end and hooked to said window frame at its other Y end, said retainer having a part intersecting the paths of withdrawal of said louvers from said sockets in a selected range of open positions.
